SUMMARY OF THE INVENTION

The present invention relates to novel compounds, in particular novel pyridinone-derivatives that are positive allosteric modulators of metabotropic receptors—subtype 2 (“mGluR2”) which are useful for the treatment or prevention of neurological and psychiatric disorders associated with glutamate dysfunction and diseases in which the mGluR2 subtype of metabotropic receptors is involved. The invention is also directed to the pharmaceutical compositions, the processes to prepare such compounds and compositions and the use of such compounds for the prevention and treatment of such diseases in which mGluR2 is involved.

BACKGROUND OF THE INVENTION

Glutamate is the major amino-acid transmitter in the mammalian central nervous system (CNS). Glutamate plays a major role in numerous physiological functions, such as learning and memory but also sensory perception, development of synaptic plasticity, motor control, respiration, and regulation of cardiovascular function.

Furthermore, glutamate is at the centre of several different neurological and psychiatric diseases, where there is an imbalance in glutamatergic neurotransmission.

Glutamate mediates synaptic neurotransmission through the activation of ionotropic glutamate receptors channels (iGluRs), the NMDA, AMPA and kainate receptors which are responsible for fast excitatory transmission (Nakanishi et al., (1998) Brain Res Brain Res Rev., 26:230-235).

In addition, glutamate activates metabotropic glutamate receptors (mGluRs) which have a more modulatory role that contributes to the fine-tuning of synaptic efficacy.

The mGluRs are seven-transmembrane G protein-coupled receptors (GPCRs) belonging to family 3 of GPCRs along with the calcium-sensing, GABAb, and pheromone receptors.

Glutamate activates the mGluRs through binding to the large extracellular amino-terminal domain of the receptor, herein called the orthosteric binding site. This binding induces a conformational change in the receptor which results in the activation of the G-protein and intracellular signalling pathways.

The mGluR family is composed of eight members. They are classified into three groups (group I comprising mGluR1 and mGluR5; group II comprising mGluR2 and mGluR3; group III comprising mGluR4, mGluR6, mGluR7, and mGluR8) according to sequence homology, pharmacological profile, and nature of intracellular signalling cascades activated (Schoepp et al. (1999) Neuropharmacology, 38:1431-76).

Among mGluR members, the mGluR2 subtype is negatively coupled to adenylate cyclase via activation of Gai-protein, and its activation leads to inhibition of glutamate release in the synapse (Cartmell & Schoepp (2000) J Neurochem 75:889-907). In the CNS, mGluR2 receptors are abundant mainly throughout cortex, thalamic regions, accessory olfactory bulb, hippocampus, amygdala, caudate-putamen and nucleus accumbens (Ohishi et al. (1998) Neurosci Res 30:65-82).

Activating mGluR2 was shown in clinical trials to be efficacious to treat anxiety disorders (Levine et al. (2002) Neuropharmacology 43: 294; Holden (2003) Science 300:1866-68; Grillon et al. (2003) Psychopharmacology 168:446-54; Kellner et al. (2005) Psychopharmacology 179: 310-15). In addition, activating mGluR2 in various animal models was shown to be efficacious, thus representing a potential novel therapeutic approach for the treatment of schizophrenia (reviewed in Schoepp & Marek (2002) Curr Drug Targets. 1:215-25), epilepsy (reviewed in Moldrich et al. (2003) Eur J. Pharmacol. 476:3-16), migraine (Johnson et al. (2002) Neuropharmacology 43:291), addiction/drug dependence (Helton et al. (1997) J Pharmacol Exp Ther 284: 651-660), Parkinson's disease (Bradley et al (2000) J. Neurosci. 20(9):3085-94), pain (Simmons et al. (2002) Pharmacol Biochem Behav 73:419-27), sleep disorders (Feinberg et al. (2002) Pharmacol Biochem Behav 73:467-74) and Huntington's disease (Schiefer et al. (2004) Brain Res 1019:246-54).

To date, most of the available pharmacological tools targeting mGluRs are orthosteric ligands which activate several members of the family as they are structural analogs of glutamate (Schoepp et al. (1999) Neuropharmacology, 38:1431-76).

A new avenue for developing selective compounds acting at mGluRs is to identify molecules that act through allosteric mechanisms, modulating the receptor by binding to a site different from the highly conserved orthosteric binding site.

Positive allosteric modulators of mGluRs have emerged recently as novel pharmacological entities offering this attractive alternative. This type of molecule has been discovered for several mGluRs (reviewed in Mutel (2002) Expert Opin. Ther. Patents 12:1-8). In particular molecules have been described as mGluR2 positive allosteric modulators (Johnson M P et al. (2003) J Med. Chem. 46:3189-92; Pinkerton et al. (2004) J Med. Chem. 47:4595-9).

WO2004092135 (NPS & Astra Zeneca), WO04018386 (Merck) and WO0156990 (Eli Lilly) describe respectively phenyl sulfonamid, acetophenone and pyridylmethyl sulfonamide derivatives as mGluR2 positive allosteric modulators. However, none of the specifically disclosed compounds are structurally related to the compounds of the invention.

It was demonstrated that such molecules do not activate the receptor by themselves (Johnson M P et al. (2003) J Med. Chem. 46:3189-92; Schaffhauser et al. (2003) Mol. Pharmacol. 64:798-810). Rather, they enable the receptor to produce a maximal response to a concentration of glutamate which by itself induces a minimal response. Mutational analysis have demonstrated unequivocally that the binding of mGluR2 positive allosteric modulators does not occur at the orthosteric site, but instead at an allosteric site situated within the seven transmembrane region of the receptor (Schaffhauser et al. (2003) Mol. Pharmacol. 64:798-810).

Animal data are suggesting that positive allosteric modulators of mGluR2 have the same effects in anxiety and psychosis models as those obtained with orthosteric agonists. Allosteric modulators of mGluR2 were shown to be active in fear-potentiated startle (Johnson et al. (2003) J Med Chem. 46:3189-92; Johnson et al. (2005) Psychopharmacology 179:271-83), and in stress-induced hyperthermia (Johnson et al. (2005) Psychopharmacology 179:271-83) models of anxiety. Furthermore, such compounds were shown to be active in reversal of ketamine—(Govek et al. (2005) Bioorg Med Chem Lett 15(18):4068-72) or amphetamine—(Galici et al. (2005) J Pharm Exp Ther Fast Forward, 2005 Aug. 25, Epub ahead of print) induced hyperlocomotion, and in reversal of amphetamine-induced disruption of prepulse inhibition of the acoustic startle effect (Galici et al. J Pharm Exp Ther Fast Forward, 2005 Aug. 25, Epub ahead of print) models of schizophrenia.

Positive allosteric modulators enable potentiation of the glutamate response, but they have also been shown to potentiate the response to orthosteric mGluR2 agonists such as LY379268 (Johnson et al. (2004) Biochem Soc Trans 32:881-87) or DCG-IV (Poisik et al. (2005) Neuropharmacology 49:57-69). These data provide evidence for yet another novel therapeutic approach to treat above mentioned neurological diseases involving mGluR2, which would use a combination of a positive allosteric modulator of mGluR2 together with an orthosteric agonist of mGluR2.

Pharmaceutical Compositions

Positive allosteric modulators of mGluR2 described herein, and the pharmaceutically acceptable salts, solvates and hydrates thereof can be used in pharmaceutical preparations in combination with a pharmaceutically acceptable carrier or diluent. Suitable pharmaceutically acceptable carriers include inert solid fillers or diluents and sterile aqueous or organic solutions. The positive allosteric modulators of mGluR2 will be present in such pharmaceutical compositions in amounts sufficient to provide the desired dosage amount in the range described herein. Techniques for Formulation and administration of the compounds of the instant invention can be found in Remington: the Science and Practice of Pharmacy, 19^(th) edition, Mack Publishing Co., Easton, Pa. (1995).

The amount of positive allosteric modulators of mGluR2, administered to the subject will depend on the type and severity of the disease or condition and on the characteristics of the subject, such as general health, age, sex, body weight and tolerance to drugs. The skilled artisan will be able to determine appropriate dosages depending on these and other factors. Effective dosages for commonly used CNS drugs are well known to the skilled person. The total daily dose usually ranges from about 0.05-2000 mg.

The present invention relates to pharmaceutical compositions which provide from about 0.01 to 1000 mg of the active ingredient per unit dose. The compositions may be administered by any suitable route. For example orally in the form of capsules, etc. . . . , parenterally in the form of solutions for injection, topically in the form of onguents or lotions, ocularly in the form of eye-drops, rectally in the form of suppositories, intranasally or transcutaneously in the form of delivery system like patches.

For oral administration, the positive allosteric modulators of mGluR2 thereof can be combined with a suitable solid or liquid carrier or diluent to form capsules, tablets, pills, powders, syrups, solutions, suspensions and the like.

The tablets, pills, capsules, and the like contain from about 0.01 to about 99 weight percent of the active ingredient and a binder such as gum tragacanth, acacias, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid, a lubricant such as magnesium stearate; and a sweetening agent such as sucrose lactose or saccharin. When a dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as a fatty oil.

Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. A syrup or elixir may contain, in addition to the active ingredient, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye and a flavoring such as cherry or orange flavor.

For parenteral administration the disclosed positive allosteric modulators of mGluR2 can be combined with sterile aqueous or organic media to form injectable solutions or suspensions. For example, solutions in sesame or peanut oil, aqueous propylene glycol and the like can be used, as well as aqueous solutions of water-soluble pharmaceutically-acceptable salts of the compounds. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

In addition, to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation, for example, subcutaneously or intramuscularly or by intramuscular injection. Thus, for example, as an emulsion in an acceptable oil, or ion exchange resins, or as sparingly soluble derivatives, for example, as sparingly soluble salts.

Preferably disclosed positive allosteric modulators of mGluR2 or pharmaceutical formulations containing these compounds are in unit dosage form for administration to a mammal. The unit dosage form can be any unit dosage form known in the art including, for example, a capsule, an IV bag, a tablet, or a vial. The quantity of active ingredient in a unit dose of composition is an effective amount and may be varied according to the particular treatment involved. It may be appreciated that it may be necessary to make routine variations to the dosage depending on the age and condition of the patient. The dosage will also depend on the route of administration which may be by a variety of routes including oral, aerosol, rectal, transdermal, subcutaneous, intravenous, intramuscular, intraperitoneal and intranasal.

Pharmacology

The compounds provided in this invention are positive allosteric modulators of metabotropic receptors, in particular they are positive allosteric modulators of mGluR2. The compounds of the present invention do not appear to bind to the glutamate recognition site, the orthosteric ligand site, but instead to an allosteric site within the seven transmembrane region of the receptor. In the presence of glutamate or an agonist of mGluR2, the compounds of this invention increase the mGluR2 response. The compounds provided in this invention are expected to have their effect at mGluR2 by virtue of their ability to increase the response of such receptors to glutamate or mGluR2 agonists, enhancing the response of the receptor. Hence, the present invention relates to a compound for use as a medicine, as well as to the use of a compound according to the invention or a pharmaceutical composition according to the invention for the manufacture of a medicament for treating or preventing a condition in a mammal, including a human, the treatment or prevention of which is affected or facilitated by the neuromodulatory effect of mGluR2 allosteric modulators, in particular positive mGluR2 allosteric modulators.

Preferably, the central nervous system disorder is a substance-related disorder selected from the group of alcohol abuse, alcohol dependence, alcohol withdrawal, alcohol withdrawal delirium, alcohol-induced psychotic disorder, amphetamine dependence, amphetamine withdrawal, cocaine dependence, cocaine withdrawal, nicotine dependence, nicotine withdrawal, opioid dependence and opioid withdrawal.

Preferably, the central nervous system disorder is an eating disorder selected from the group of anorexia nervosa and bulimia nervosa.

Preferably, the central nervous system disorder is a mood disorder selected from the group of bipolar disorders (I & II), cyclothymic disorder, depression, dysthymic disorder, major depressive disorder and substance-induced mood disorder.

Preferably, the central nervous system disorder is migraine.

Preferably, the central nervous system disorder is epilepsy or a convulsive disorder selected from the group of generalized nonconvulsive epilepsy, generalized convulsive epilepsy, petit mal status epilepticus, grand mal status epilepticus, partial epilepsy with or without impairment of consciousness, infantile spasms, epilepsy partialis continua, and other forms of epilepsy.

At present, the fourth edition of the Diagnostic & Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association provides a diagnostic tool for the identification of the disorders described herein. The person skilled in the art will recognize that alternative nomenclatures, nosologies, and classification systems for neurological and psychiatric disorders described herein exist, and that these evolve with medical and scientific progresses.

Because such positive allosteric modulators of mGluR2, including compounds of Formula (I), enhance the response of mGluR2 to glutamate, it is an advantage that the present methods utilize endogenous glutamate.

Because positive allosteric modulators of mGluR2, including compounds of Formula (I), enhance the response of mGluR2 to agonists, it is understood that the present invention extends to the treatment of neurological and psychiatric disorders associated with glutamate dysfunction by administering an effective amount of a positive allosteric modulator of mGluR2, including compounds of Formula (I), in combination with an mGluR2 agonist.

The compounds of the present invention may be utilized in combination with one or more other drugs in the treatment, prevention, control, amelioration, or reduction of risk of diseases or conditions for which compounds of Formula (I) or the other drugs may have utility, where the combination of the drugs together are safer or more effective than either drug alone.

Methods of Synthesis

The compounds according to the invention, in particular the compounds according to the Formula (I), (II), (II-a), (II-b), (II-c), (II-c1), (II-c2), (II-c3), (III), (III-a), (III-b), (III-c), (III-c1), (III-c2), (III-c3), (IV), (V), (V-a) and (V-b), may be prepared by methods known in the art of organic synthesis or by the following synthesis schemes. In all of the schemes described below it is understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with the general principles of organic chemistry. Protecting groups are manipulated according to standard methods (T. W. Green and P. G. M. Wuts, 1991, Protecting Groups in Organic Synthesis, John Wiley & Sons, Inc.). These groups are then removed at a convenient stage of the synthesis using methods that are readily apparent to those skilled in the art.

The compounds according to the invention may be represented as a mixture of enantiomers which may be resolved into their individual R- or S-enantiomers. If for instance, a particular enantiomer is required it may be prepared by asymmetric synthesis or by derivation with a chiral auxiliary and the resulting diastereomeric mixture separated. The auxiliary group can then be cleaved to provide the desired pure enantiomers. Alternatively, where the molecule contains a basic functional group such as an amino or an acidic functional group such as a carboxyl functional group, resolution may be performed by fractional crystallization from various solvents as the salt of an optical active acid or by other methods known in the literature (e.g. chiral column chromatography).

Resolution of the final product, an intermediate or a starting material may be performed by any suitable method known in the art (E. L. Eliel, S. H. Wilen and L. N. Mander, 1984, Stereochemistry of Organic Compounds, Wiley-Interscience).

Many of the heterocyclic compounds of Formula (I) to (V-b) where M₁ or M₂ is a heteroaromatic or heterocyclic group may be prepared using synthetic routes well known in the art (A. R. Katrizky and C. W. Rees, 1984, Comprehensive Heterocyclic Chemistry, Pergamon Press).

The synthesis of mGluR2 modulators disclosed herein are shown in the following synthetic schemes. Specific conditions for carrying out these reactions are provided in the examples. In one embodiment, the invention provides compounds of Formula V, where the V₁T₁M₁ group can be introduced by alkylation (N—C, bond formation) using the appropriate starting materials (i.e. pyridine derivatives or pyridinone derivatives). The V₁T₁M₁ group can be introduced by an alkylation (O—C or N—C, bond formation), a reductive amination (C—N, bond formation), or by displacement of a leaving group Cl, Br, I or OP, where OP is defined as a leaving group (e.g. tosylate, and mesylate) (C—N or C—O, bond formation). C—N, C—O and C—C bond formation are well understood by a person skilled in the art of organic chemistry. The synthetic schemes described below show exemplified approaches to compounds of the present invention but these routes should not be taken as the only possible synthetic routes to compounds of the present invention.

Pyridinones g1 are commercially available or may be synthesized in ways described in the literature (Synthesis, 2002, 79-82; Tetrahedron Asymmetry, 1998, 2027; J. Heterocycl. Chem., 1974, 251; Synth. Commun., 1994, 1367). Selective bromination of a suitably substituted pyridine g1 leads to bromopyridine g2. It is well known that such brominations can lead to isomers (Bioorg. Med. Chem. Lett., 2002, 197-202) which can be separated by crystallization or column chromatography. The group V₁T₁M₁ can then be introduced in one step by alkylation using an elaborated W—V₁T₁M₁ group (where W is Cl, Br or OP) or alternatively, a HO—V₁T₁M₁ group using Mitsunobu conditions (Tetrahedron Letters, 1994, 2819-2822). It is described in the literature that this procedure may give undesired O-alkylated product which can be separated by crystallization or column chromatography.

Alternatively, the group V₁T₁M₁ can be introduced by reaction of a suitably substituted 2-methoxypyridine with an elaborated W—V₁T₁M₁ where W is Cl, Br or OP (Scheme 2).

Suitably substituted, means in the context of the invention, substituents as defined in the list of preferred substituents or substituent which can be precursor of the aforementioned preferred substituents and are therefore protected in a manner that a person skilled in the art would recognize.

The introduction of the V₂T₂M₂ can be done through carbon-carbon bond formation (Scheme 3).

-   -   Using a boronic acid under Suzuki-Miyaura conditions (Chem.         Rev., 1995, 95, 54, 263) where V₂T₂ are bonds and M₂ is aryl,         heteroaryl, cycloalkenearyl or cycloalkeneheteroaryl (Method A).     -   Using a suitable alkylidinyl group under Sonogashira condition         (J. Med. Chem., 2000, 43, 4288-4312) where V₂T₂ is an         alkylidinyl group and M₂ is aryl, alkylaryl, heteroaryl or         alkylheteroaryl (Method B).     -   Using a suitable alkylidenyl group under Heck condition where         V₂T₂ is alkylidenyl group and M₂ is aryl, alkylaryl, heteroaryl         or alkylheteroaryl.

The Suzuki-Miyaura (Method A, Scheme 3) carbon-carbon coupling reaction requires a catalyst such as PdCl₂(PPh₃)₂, Pd(PPh₃)₄, Pd₂(dba)₃, Pd₂(dppf) or Pd(OAc)₂ and an aqueous or non-aqueous base such as sodium carbonate, potassium carbonate, sodium hydroxide or cesium fluoride in a suitable solvent such as dioxane, toluene, dimethoxyethane or DMF. The Sonogashira (Method B, Scheme 3) carbon-carbon coupling reaction requires a catalyst such as PdCl₂(PPh₃)₂, Pd(PPh₃)₄ or Pd(OAc)₂ in a suitable solvent such as DMF, acetonitrile or benzene. Typically, a co-catalyst such as copper (I) iodide and a base such as triethylamine, diisopropylamine, or KOAc will also be present in the reaction mixture. The Suzuki-Miyaura and Sonogashira reactions typically react at temperatures ranging from 0° C. to 150° C. Typically, the reaction is maintained for 1 to 24 hours, with 12 hours usually being sufficient. The product of the reaction can be isolated and purified using standard techniques such as solvent extraction, column chromatography, crystallization, distillation and sublimation.

For a person skilled in the art of organic chemistry it is well understood that compound g7 can be hydrogenated under catalytic conditions using for example Pd/C and H₂ or ammonium formate (as hydrogen source) to afford the partially reduced analogs g8 which are also part of this invention. It is noteworthy that a full hydrogenated version cannot be achieved under these conditions and therefore another approach should be envisaged to achieve fully reduced compounds (Scheme 8).

The inventors are aware that some chemical groups within V₁T₁M₁ may not be compatible with the aforementioned carbon-carbon bond forming reaction (i.e. Sonogashira, Heck or Suzuki-Miyaura). Therefore, the V₁T₁M₁ group can be introduced later in the synthesis (Scheme 4, Method A) and for example the Sonogashira reaction could be performed in the first step on a suitably substituted 2-methoxypyridine 5-boronic acid g9. The synthesis of such boronic acid is well described in the literature (J. Org. Chem., 2002, 67, 7541-7543) from commercial precursors with aryl and heteroaryl triflates or bromides. Aryl and heteroaryl bromides are available from commercial sources. The synthesis can also be performed from a suitably substituted 2-methoxypyridine having in position 5 an halide or a triflate reacting in a Suzuki-Miyaura reaction with a boronic compound Q-M₂ where Q is B(OR)₂. (Method B)

Likewise, the V₂T₂M₂ (in this case V₂ and T₂ are bonds and M₂ is aryl, alkenearyl, aryl or heteroaryl) group can be introduced onto g2 in the first step (Scheme 5), to yield compound g12 which is then subjected to W—V₁T₁M₁ under conditions similar to those described in Scheme 1, Step 2.

For a person skilled in the art of organic chemistry it is well understood that functionalities present in compound g5 (where Y is COOMe, CN or CHO) may be further transformed into compound g13 as exemplified where Y is COOMe (Scheme 6).

The acid compound generated from the ester g5 is an excellent anchoring point for heterocycle formation such as benzothiazole, oxadiazole, benzoxazole or isoxazole. The composition of the invention is not limited only to the aforementioned heterocycles but extends to our preferred list of heterocycles which may be synthesized through a similar scheme. (A. R. Katrizky and C. W. Rees, 1984, Comprehensive Heterocyclic Chemistry, Pergamon Press).

For one skilled in the art of organic chemistry it is well understood that functionalities present in compound g5 (where Y is COOMe, CN or CHO) may be further transformed into compounds g14, g15, g16 and g17 (Scheme 7).

The reductive amination to afford compound g14 is well documented in the literature (Helv. Chim. Acta, 1998, 81, 1754). The synthesis of alcohol g15 may utilize organometallic reagents such as the Grignard reagent exemplified here. However, many alternative organometallic reagents may be used and their preparation and use is well exemplified in the literature (M. Schlosser, 1994, Organometallics in Synthesis, John Wiley & Sons, Inc.). Compound g15 can be subsequently transformed into ketone g16 via oxidation or into alkyl g17 via reductive elimination.

The inventors are aware that for specific compounds of the invention for instance compound g19 neither compound g5 nor compound g3 are compatible intermediates, therefore, compound g4 would be a suitable starting material (Scheme 8).

All the methods used in Scheme 8 have been described in previous schemes.

A person skilled in the art of organic chemistry would recognise that the V₁T₁M₁ group assembly may be constructed stepwise to afford compounds g20 and g22 (Scheme 9).

The acid moiety present in g21 is an excellent anchoring point for heterocycle formation such as benzothiazole g23, benzoxazole g24, oxadiazole g25 and isoxazole (Scheme 10) which are also compounds of this invention. The composition of the invention is not limited only to the aforementioned heterocycles but extend to our preferred list of heterocycles which can be synthesized through a similar scheme (A. R. Katrizky and C. W. Rees, 1984, Comprehensive Heterocyclic Chemistry, Pergamon Press; Chem. Pharm. Bull., 1999, 47, 120-122).

In another embodiment, the invention provides compounds of Formula (II) (Scheme 11). The synthesis of starting materials (i.e. isoquinolin-1-one derivatives) when not commercially available are well described in the literature (Chem. Ber., 1972, 3726-3747; Chem. Pharm. Bull., 1982, 1680-1691, Chem. Pharm. Bull., 1986, 2754-2759). For a person skilled in the art of organic chemistry it is well understood that the preferred substituents as defined in the claims can be introduced using similar chemistry. V₁T₁M₁ may be introduced using an elaborated W—V₁T₁M₁ (where W is Cl, Br or OP) in the presence of base such as NaH, K₂CO₃ or NaHMDS in a suitable solvent such as THF or DMF. It is noteworthy that these procedures may lead to undesired O-alkylated product which can be separated by crystallization or column chromatography.

In another embodiment, the invention provides compounds of Formula (III) (Scheme 12). The syntheses of similar compounds are well described in the literature (Magn. Reson. Chem., 26, 1988, 511-517; J. Chem. Soc. Perkin Trans., 1, 1980, 197-202; J. Heterocycl. Chem., 1983, 1707-1708, Heterocycles, 1997, 483-492). For a person skilled in the art of organic chemistry it is well understood that preferred substituents as defined in the claims can be introduced using similar chemistry. V₁T₁M₁ can be introduced using an elaborated W—V₁T₁M₁ (where W is Cl, Br or OP) in presence of base such as NaH or K₂CO₃ or alternatively, with HO—V₁T₁M₁ using Mitsunobu condition (Tetrahedron Letters, 1994, 2819-2822) It is noteworthy that this procedure may lead to undesired O-alkylated product which can be separated by crystallization or column chromatography.

In another embodiment of the invention provides compounds of Formula (IV) (Scheme 13).

Alkylation of 2,4-dihydroxypyridine (commercially available) with a substituted benzyl halide is achieved using a base such as K₂CO₃ in a suitable solvent such as THF, CH₃CN or DMF under heating at 80° C. This transformation may lead to a mixture of products which can then be separated to isolate intermediate g27. The deprotection of the hydroxybenzyl moiety can be selectively achieved using Pd/C and H₂ or ammonium formate (as hydrogen source). The subsequent alcohol can either be alkylated as described previously or transformed into a triflate. Triflate g28 is a rather sensitive molecule and is used in the carbon-carbon bond formation (exemplified here with a Suzuki-Miyaura reaction or Sonogashira coupling, Scheme 3).

In another embodiment of the present invention compounds of Formula (V) may be prepared in accordance with Scheme 14. Compound g31 can be deprotected in the presence of BBr₃ (J. Med. Chem., 1997, 40, 2085-2101). The resulting alcohol g32 can be alkylated by XCH₂R where X may be a good leaving group such as Cl, Br, I or OP in the presence of a base such as K₂CO₃, Cs₂CO₃ or NaH in a suitable solvent such as DMF, acetone or tetrahydrofuran at an appropriate temperature or acylated by XCOR where X is Cl in the presence of a base such as Et₃N or DIEA in a suitable solvent.

In another embodiment of the present invention, the compounds of Formula (V) may be prepared according to the synthetic sequences illustrated in Scheme 15. Compound g35 may be hydrolyzed by standard procedures followed by reaction with a primary or secondary amine in order to lead to compound g37 (Scheme 6). Compounds g36 and g38 represent an excellent anchoring point (acid, nitrile or amide) for heterocycle formation such as thiazole, oxadiazole, oxazole or isoxazole. The composition of the invention is not limited only to the aforementioned heterocycles but extends to our preferred list of heterocycles which can be synthesized through a similar scheme (A. R. Katrizky and C. W. Rees, 1984, Comprehensive Heterocyclic Chemistry, Pergamon Press).

In another embodiment of the present invention, compounds of Formula (V) may be prepared in accordance with Scheme 16. For a person skilled in the art of organic chemistry it is well understood that aldehyde g4 can be reduced using LiAlH₄ to afford the alcohol g40 which can be alkylated using either R′X (where X is Cl, Br or OP) in the presence of a base such as K₂CO₃, Cs₂CO₃ or NaH in a suitable solvent such as DMF, acetone or tetrahydrofuran or alternatively, using R′OH with Mitsunobu conditions as described in Scheme 1. Another way to synthesize compound g42 is to first alkylate compound g4 then reduce and finally to alkylate a second time.

In one embodiment of the present invention compounds of Formula (V-b) may be prepared according to the synthetic sequences illustrated in Scheme 17. Compound g3 can be transformed into boronic esters via metal-halogen exchange in the presence of Pd(PPh₃)₄. The resulting boronic esters can be coupled to M₂ via Suzuki-Miyaura coupling as described in Scheme 3.

In another embodiment of the present invention, compounds of Formula (V) may be prepared in accordance with Scheme 18. For one skilled in the art of organic chemistry it is well understood that ester g44 can be reduced using LiAlH₄ to afford the alcohol g45.

In another embodiment of the present invention, the compounds of Formula (V) may be also prepared according to the synthetic sequences illustrated in Scheme 19. Compound g3 can be submitted to Suzuki-Miyaura coupling with boronic compounds being substituted by a protected amino moiety. Then in Method A, the removal of the Boc group in compound g46 may be achieved under classical conditions well known in the art such as HCl or TFA. The resulting primary amine can then be either acylated by standard procedure or submitted to reductive amination (Scheme 7). And in Method B, compound g46 can be submitted first to alkylation using preferentially NaH as base and tetrahydrofurane as organic solvent followed by deprotection under acidic conditions (for example the reaction can be done in an organic solvent such as DCM with an acid such as TFA typically at room temperature to give compound g48b.

The synthesis of alcohol g50 may requires organometallic reagents such as the Grignard reagent exemplified here (Scheme 20). However, many alternative organometallic reagents may be used and their preparation and use is well exemplified in the literature (M. Schlosser, 1994, Organometallics in Synthesis, John Wiley & Sons, Inc.).

Another embodiment of the invention provides compounds of Formula (IV) (exemplified in Scheme 21). Substituted 3-bromo-pyridine or 3-iodopyridine g51 can be subjected to directed ortho metalation at low temperatures (e.g. −78° C.) in a solvent such as. THF or diethyl ether with lithium diisopropylamide and subsequently quenched with an electrophilic halogen source (e.g. Br₂ or I₂). 4-halopyridine g52 can then be functionalized by carbon-carbon bond forming reaction (Step 2, exemplified here by Suzuki-Miyaura or Stille reaction) under condition similar to those described in Scheme 3. Displacement of 2-halopyridine g53 by sodium methoxide in methanol yielded 2-methoxypyridine g54. Subsequent alkylation was then performed as described in Scheme 2 to yield pyridinone g55.

Another embodiment of the invention provides compounds of Formula (V) (exemplified in Scheme 22). Method A, substituted 5-bromo-2-methoxy-pyridine g4 was subjected to lithium-halogen exchange at −78° C. in an a solvent such as THF or diethyl ether with butyl lithium and quenched with a substituted alkyl bromide (M₂V₂T₂X) to give compound g56. Alkylation was then performed as described in example 1 to give compound g57.

In a similar manner, compound g4 can be involved in a Buchwald reaction (Method B) with an amine in conditions known in the art using palladium, a suitable catalyst and a ligand to afford after alkylation compound g57 (where V₂═NH or N-alkyl).

Another embodiment of the invention provides compounds of Formula (V-b) (Scheme 23). Step 1, nucleophilic displacement of 2-halopyridine g58 (where X═I, Br, Cl or F) by sodium methoxide in methanol yielded 2-methoxypyridine g59. Bromination was achieved using bromine, aqueous potassium bromide, potassium hydroxide and water (Step 2). The bromopyridine g60 was then functionalized by carbon-carbon bond forming reaction (Step 3, exemplified here by Suzuki-Miyaura reaction) under conditions similar to those described in Scheme 3. Step 4, alkylation was then performed as described in Scheme 2 to give compound g62.

Another embodiment of the invention provides compounds of Formula (V-b) (Scheme 24). Step 1, substituted pyridine g2 (where X=Br, I or TfO) was first functionalized by carbon-carbon bond forming reaction (Step 1, exemplified here by Suzuki-Miyaura reaction) under conditions similar to those described in Scheme 3. Alkylation was performed with alkyl halides (W—R₁), NaI in MeCN at 70° C. (Step 2). The resulting alcohol g63 was alkylated using standard Williamson ether synthesis (Step 3, NaH, DMF and alkyl halide at 0° C.) to yield compound g64.

Another embodiment of the invention provides compounds of Formula (V-b) (Scheme 25). Alkylation of 2-hydroxypyridine g2 was performed as described in example 1. Step 2, bromopyridine 3 was first functionalized by carbon-carbon bond forming reaction (exemplified here by Suzuki-Miyaura reaction) under conditions similar to those described in Scheme 3. The alcohol g65 was then alkylated to obtain compound g66. Or bromination of compound g65 was achieved using PPh₃, NBS and Et₂0 at −20° C. (Step 3). The resulting bromide was alkylated using standard Williamson ether synthesis to yield ether g66 (Step 4, alkyl alcohol, NaH and DMF at 0° C.).

Another embodiment of the invention provides compounds of Formula (V-b) (Scheme 26). Step 1, lithium-halogen exchange on substituted 5-bromo-2-methoxy-pyridine g4 at −78° C. in THF with butyl lithium was reacted with a substituted carbonyl compounds. The resulting alcohol g67 was then eliminated using MsCl, TEA and DCM at room temperature (Step 2). The olefin g68 was then hydrogenated using standard conditions (H₂, Pd/C in EtOH). Finally, the compound was alkylated as described for Scheme 2 to give compound g70.

Another embodiment of the invention provides compounds of Formula (I) (Scheme 27). Where W is Cl, Br, I and OTf, pyrazine g71 was alkylated using standard conditions (Step 1). NaH, DMF or K₂CO₃, MeCN, at room temperature, elevated temperatures or with microwave irradiation. Alternatively, where W is OH, alkylation could be performed by Mitsunobu reaction using, DEAD, PPh₃, THF at room temperature or 60° C. The bromopyrazine g72 was then subjected to a carbon-carbon bond forming reaction (Step 2, exemplified here by Suzuki-Miyaura reaction) under conditions similar to those described in Scheme 3 to give compound g73.

In another embodiment of the present invention, the compounds of Formula (II) may be prepared according to the synthetic sequences illustrated in Scheme 28. Isoquinoline g74 can be converted into isoquinolone g76 (Heterocycles, 1996, 42, 415) via oxidation with mCPBA followed by rearrangement of the N-oxide in the presence of acetic anhydride and then by basic sodium hydroxide cleavage. Finally, the resulting isoquinolone g76 can be alkylated as described in Scheme 1 and submitted to Buchwald coupling (if V₂=NR) as in Scheme 22. It is obvious that introduction of V₁T₁M₁ or V₂T₂M₂ groups can be done through the same process as described earlier.

In another embodiment of the present invention, the compounds of Formula (II) may be prepared according to the synthetic sequences illustrated in Scheme 29. Compound g77 can be submitted to a Sonogashira coupling and reduced (Scheme 8) to yield compound g79. Then the isoquinoline may be transformed into alkylated isoquinolone g82 as presented in Scheme 29.

In another embodiment of the present invention, compounds of Formula (V-b) can be prepared in accordance with Scheme 30. Bromopyridine g83 can be functionalized by carbon-carbon bond forming reaction (exemplified here by Suzuki-Miyaura reaction) under condition similar to those described in Scheme 3. The resulting pyridine g84 can be lithiated by strong base such as butyl lithium or LDA in THF at low temperatures (e.g. −78° C.) and subsequently quenched with paraformaldehyde to give alcohol g86 after workup. N-Alkylation by NaI in acetonitrile at elevated temperatures using W— V₁T₁M₁ yields compound g86. The resulting alcohol g86 can be alkylated by the methods described in Scheme 24, step 3.

In another embodiment of the present invention, compounds of Formula (V-b) can be prepared in accordance with Scheme 31. Pyridine g84 was prepared as described in Scheme 30. Bromination with NBS under UV light in CCl₄ at reflux gave compound g88. Alkylation using ROH and sodium methoxide at reflux gave compound g89. The resulting alcohol g89 can then be alkylated by the methods described in Scheme 1.

Compound g93 (Scheme 32) can be synthesized from either bromide g91 or alcohol g92 using any one of the procedures known in the art, for example, using a copper catalyzed coupling reaction conditions when R is aryl or via a Mitsunobu reaction conditions when R is alkyl respectively. Finally, the resulting ether g93 can be alkylated with for example alkyl halide, in an organic solvent such as acetonitrile or dimethylformamide and with a base such as K₂CO₃.

Compound g96 (Scheme 33) can be synthesized from pyridine g95 (prepared as described in Schemes 1 and 3) via halogen exchange. Then the iodopyridine may be coupled through Sonogashira or Heck conditions to alkynes or alkenes respectively. The resulting insaturated compound g97 can then be reduced as exemplified earlier by hydrogenation to give compound g98.

In another embodiment of the present invention, the compounds of Formula (II) may be prepared according to the synthetic sequences illustrated in Scheme 34. Isoquinoline g99 can be converted into his N-oxide g100 via oxidation in the presence of MCPBA followed by standard alkylation. Rearrangement of N-oxide g101 in the presence of acetic anhydride and basic sodium hydroxide cleavage yielded isoquinolone g102. Finally, the resulting isoquinolone g102 can be alkylated as described in Scheme 1. It is obvious that introduction of V₁T₁M₁ or V₂T₂M₂ groups can be done through the same process as described earlier.

Physico-Chemical Data

¹H NMR spectra were recorded on Bruker 500 MHz or 300 MHz. Chemical shifts are expressed in parts of million (ppm, 8 units). Coupling constants are in units of hertz (Hz). Splitting patterns describe apparent multiplicities and are designated as s (singulet), d (doublet), t (triplet), q (quadruplet), m (multiplet).

LCMS were recorded on a Waters Micromass ZQ 2996 system by the following conditions. Column 3.0*50 mm stainless steel packed with 5 μm XTerra RP C-18; flow rate 1 ml/min; mobile phase: A phase=0.1% formic acid in water, B phase=0.07% formic acid in acetonitrile. 0-0.5 min (A: 95%, B: 5%), 0.5-6.0 min (A: 0%, B: 100%), 6.0-6.5 min (A: 95%, B: 5%), 6.5-7 min (A: 95%, B: 5%); UV detection Diode Array: 200-400 nm; Injection volume: 3 μl. For the ACE-C₁₈ column (3.0 μm, 4.6×30 mm) from Advanced Chromatography Technologies, with a flow rate of 1.5 mL/min. The standard gradient conditions used are: 80% A (0.5 g/l ammonium acetate solution), 10% B (acetonitrile), 10% C (methanol) to 50% B and 50% C in 6.5 min., to 100% B at 7 min. and equilibrated to initial conditions at 7.5 min. until 9.0 min. A 5 μL volume of the sample was injected. In some cases sodium bicarbonate (1 g/l) was used as buffer. All mass spectra were taken under electrospray ionisation (ESI) methods.

Most of the reaction were monitored by thin-layer chromatography on 0.25 mm Macherey-Nagel silica gel plates (60F-2254), visualized with UV light. Flash column chromatography was performed on silica gel (220-440 mesh, Fluka).

Melting point determination was performed on a Buchi B-540 apparatus.

Pharmacology

The compounds provided in the present invention are positive allosteric modulators of mGluR2. As such, these compounds do not appear to bind to the orthosteric glutamate recognition site, and do not activate the mGluR2 by themselves. Instead, the response of mGluR2 to a concentration of glutamate or mGluR2 agonist is increased when compounds of Formula (I) are present. Compounds of Formula (I) are expected to have their effect at mGluR2 by virtue of their ability to enhance the function of the receptor. The behavior of positive allosteric modulators, more particular the ones described by Formula (I), at mGluR2 is shown in Example A, which is suitable for the identification of such compounds.

Example A [³⁵S]GTPγS Bindin2 Assay

The [³⁵S]GTPγS binding is a functional membrane-based assay used to study G-protein coupled receptor (GPCR) function. This method is using a binding assay to assess the initial step in receptor-mediated G protein activation in membranes prepared from cells expressing recombinant GPCR or using membranes from discrete area of the rat brain. In brief, the assay is measuring the activation of G proteins by catalyzing the exchange of guanosine 5′-diphosphate (GDP) by guanosine 5′-triphosphate (GTP) at the α subunit. The GTP-bounded G proteins dissociate into two subunits, Gα-GTP and G3γ, which in turn regulate intracellular enzymes and ion channels. GTP is rapidly hydrolysed by the Gα-subunit (GTPases) and the G protein is deactivated and ready for new GTP exchange cycle (Harper (1998) Curr Protoc Pharmacol 2.6.1-10, John Wiley & Sons, Inc.). [³⁵S]GTPγS, a non-hydrolyzed analogue of GTP, is used for this purpose.

This method is widely used to study receptor activation of G protein in membranes prepared from rat brain tissue, including mGluR2 receptors (Schaffhauser et al 2003, Pinkerton et al, 2004). mGluR2 receptors are expressed in the rat brain cortex (Mutel et al (1998) J. Neurochem. 71:2558-64; Schaffhauser et al (1998) Mol. Pharmacol. 53:228-33) and are coupled to Gai-protein, a preferential coupling for this method. The study of the pharmacological characterisation of metabotropic glutamate receptor-mediated high-affinity GTPase activity (Nishi et al (2000) Br. J. Pharmacol. 130:1664-1670) showed that the activation of G-proteins in rat cerebral cortical membranes is mediated by group II mGluRs, and in particular by mGluR2.

[³⁵S]GTPγS binding assay using cortical rat brain membranes preparation was used and adapted from Schaffhauser et al ((2003) Mol. Pharmacol. 4:798-810) for the detection of the positive allosteric modulator properties of the compounds of this invention on native rat mGluR2. In order to eliminate the possible interference with group III Gαi-protein coupled mGluRs (mGluR4, mGluR7, mGluR8; mGluR6 is not expressed in the cortex (Laurie et al (1997) Neuropharmacol. 36:145-52)), the potentiation of the response to a selective mGluR2 agonist, such as DCG-IV (Cartmell et al. (1998) Br. J. Pharmacol. 123(3):497-504) or LY379268 (Monn et al. (1999) J. Med. Chem. 42:1027-40), by compounds described in the present invention was performed.

Membrane Preparation.

Cortices were dissected out from brains of 200-300 g Sprague-Dawley rats (Charles River Laboratories, L'Arbresle, France). Tissues were homogenized in 6 volumes (vol/wt) of 10% sucrose at 4° C. using a glass-teflon homogenizer. The homogenate was centrifuged at 1250 g for 10 min, and the supernatant was centrifuged at 40,000 g for 20 min (4° C.). The pellet was resuspended in ml water using a Polytron disrupter (Kinematica AG, Luzern, Switzerland) and centrifuged for 10 min at 3000 g. (4° C.). The supernatant was centrifuged at 40,000 g for min (4° C.). The supernatant was discarded and the pellet washed twice by resuspension in 10 volumes 5 mM HEPES-KOH, pH 7.4. The homogenate was frozen and thawed twice and centrifuged at 40,000 g for 20 min. The final pellet was resuspended in 5 mM HEPES-KOH, pH 7.4 and stored at −80° C. before its use. Protein concentration was determined by the Bradford method (Bio-Rad protein assay, Reinach, Switzerland) with bovine serum albumin as standard.

[³⁵S]GTPγS Binding Assay.

Measurement of mGluR2 positive allosteric modulators properties in rat cortical membranes was performed as follows: rat cortical membrane (1.5 μg) were incubated in 96-well microplates for 15 min at 30° C. in assay buffer (50 mM HEPES pH 7.4, 100 mM NaCl, 5 mM MgCl₂, 10 μM GDP, 10 μg/ml saponin, EGTA 0.2 mM) with increasing concentrations of positive allosteric modulator (from 1 nM to 10 μM) and a minimal concentration of DCG-IV or LY379268, a selective mGluR2 agonist, that has been determined in previous experiments and that corresponds to the EC₂₀, a concentration that gives 20% of the maximal response of the agonist, and is in accordance to published data (Pin et al. (1999) Eur. J. Pharmacol. 375:277-294). Likewise, 10-point concentration-response curves of an mGluR2 selective agonist such as DCG-IV or LY379268, were tested in the absence or in the presence of 3 or 10 μM of positive allosteric modulator in order to detect a leftward-shift of the concentration-response curve of the agonist (appreciated by a decrease in the EC₅₀) and/or an increase of its maximal efficacy. After addition of 0.1 nM [³⁵S]GTPγS to achieve a total reaction volume of 200 μl, microplates were shaken for 1 min and further incubated at 30° C. for 30 min. The incubation was stopped by rapid vacuum filtration over glass-fiber filter plates (Unifilter 96-well GF/C filter plates, Perkin-Elmer, Schwerzenbach, Switzerland) microplate using a 96-well plate cell harvester (Filtermate, Perkin-Elmer, Downers Grove, USA). The Unifilter plate was washed three times with 300 μl of ice-cold wash buffer (20 mM HEPES pH 7.4, 100 mM NaCl). When filters are dried, 40 μl of liquid scintillation cocktail (Microscint 20) was added to each well. The amount of membrane-bound [³⁵S]GTPγS is measured using a 96-well plate reader (Top-Count, Perkin-Elmer, Downers Grove, USA). Non specific [³⁵S]GTPγS binding is determined in the presence of 10 μM of GTP.

Data Analysis.

The concentration-response curves of representative compounds of the present invention in the presence of EC₂₀ of mGluR2 agonist were generated using the Prism Graph-Pad program (Graph Pad Software Inc, San Diego, USA). The curves were fitted to a four-parameter logistic equation (Y=Bottom+(Top-Bottom)/(1+10̂((LogEC₅₀−X)*Hill Slope) allowing determination of EC₅₀ values. Each curve was performed using triplicate sample per data point and 10 concentrations. The concentration-response curves of a selective mGluR2 agonist in the absence or in the presence of representative compounds of the present invention were also generated using Prism Graph-Pad program (Graph Pad Software Inc, San Diego, USA). The curves were fitted to a four-parameter logistic equation (Y=Bottom+(Top-Bottom)/(1+10̂((LogEC₅₀−X)*Hill Slope) allowing determination of EC₅₀ values of the selective mGluR2 agonist. Each curve was performed using triplicate sample per data point and 10 concentrations.

Data presented in FIG. 1 represent the ability of 10 μM of Compound 4-16 to increase the [GTPγ³⁵S]binding induced by 50 nM of DCG-IV, an mGluR2 agonist.

Said compound has no statistically significant agonistic activity when tested in the absence of 50 nM DCG-IV, as compared to buffer value (0% of maximal response).

Instead, when compounds are added together with an mGluR2 agonist like glutamate or DCG-IV, the effect measured is significantly potentiated compared to the effect of the agonist alone at the same concentration. Each bar graph in FIG. 1 is the mean and S.E.M. of triplicate data points and is representative of three independent experiments.

Table 19 shows representative compounds of the present invention that were clustered into three classes according to their ability to leftward-shift the concentration-response curve of a selective mGluR2 agonist such as LY379268 and/or to increase its maximal efficacy.

Thus, the positive allosteric modulators provided in the present invention are expected to increase the effectiveness of glutamate or mGluR2 agonists at mGluR2, and therefore, these positive allosteric modulators are expected to be useful for treatment of various neurological and psychiatric disorders associated with glutamate dysfunction described to be treated herein and others that can be treated by such positive allosteric modulators.

Example B Animal Models of Schizophrenia

Phencyclidine (PCP) Model of Schizophrenia

PCP-induced increases in locomotor ambulation are a widely accepted animal model of schizophrenia. This model is based on the evidence that phencyclidine induces a schizophrenia-like syndrome in humans including increased motor behaviors, disruption of cognition and impairment of working memory (Steinpreis R E (1996) Behav Br Res. 74:45-55; Abi-Saab et al. (1998) Pharmacopsychiatry, 31:104-109). Further, it has also been shown that antipsychotic drugs that are effective in the treatment of schizophrenia reduce the locomotor activating effect of PCP (Gleason & Shannon (1997) Psychopharmacology, 129:79-84). These results demonstrate that locomotor activation induced by PCP is a useful model for screening of compounds which may be useful in the treatment of schizophrenia.

Amphetamine Model of Schizophrenia

Amphetamine-induced increases in locomotor ambulation are well known and are widely used as a model of the positive symptoms of schizophrenia. This model is based on evidence that amphetamine increases motor behaviors and can induce a psychotic state in humans (Yui et al. (2000) Ann NY Acad Sci 914:1-12). Further, it is well known that amphetamine-induced increases in locomotor activity are blocked by antipsychotics drugs that are effective in the treatment of schizophrenia (Arnt (1995) Eur J Pharmacol 283:55-62). These results demonstrate that locomotor activation induced by amphetamine is a useful model for screening of compounds which may be useful in the treatment of schizophrenia.

Subjects: The present studies were performed in accordance with the animal care and use policies of Addex Pharmaceuticals and the EEC directives on the protection of animals used for experimental and other scientific purposes (86/609/EEC and subsequent revisions). Male C57BL6/j mice (20-30 g) 7 weeks of age at the time of delivery were group housed in a temperature and humidity controlled facility on a 12 hour light/dark cycle for at least 5 days before use. Mice had access to food and water ad libitum except during locomotor activity experiments.

Assessment of locomotor (ambulatory) activity: The effects of compounds on PCP- or amphetamine-induced locomotor activation in mice were tested. Locomotor activity of mice was tested in white plastic boxes 35 cm×35 cm square with walls 40 cm in height. Locomotor activity (ambulations) was monitored by a videotracking system (VideoTrack, Viewpoint, Champagne au Mont d'Or, France) that recorded the ambulatory movements of mice. Mice were naïve to the apparatus prior to testing. On test days, test compounds (200 mg/kg i.p. (intraperitoneal)) or vehicle were administered immediately before the PCP (5 mg/kg s.c.(sub-cutaneous), amphetamine (3.0 mg/kg s.c.) or saline injection. Mice were placed into the locomotor boxes immediately after the PCP, amphetamine or saline vehicle injection and their locomotor activity, defined as the distance traveled in centimeters (cm), was measured for 60 minutes.

Compound administration: Compounds were dissolved in dimethyl sulfoxide (DMSO) (4% of final volume) and then mixed with Labrafil M1944 CS (apricot kernel oil—Gattefossé, Saint Priest, France) (40% of final volume), sterile water (56% of final volume) and Tween 80 (10 μL per 10 ml solution) and administered in a volume of 10 ml/kg. Compound-vehicle-treated mice received the equivalent volume of vehicle solution i.p. in the absence of added compound. PCP hydrochloride (Sigma, Switzerland) was dissolved in saline and was administered at a dose of 5 mg/kg s.c. in a volume of 10 ml/kg. PCP-vehicle-treated mice received an equal volume of saline vehicle injected s.c.

Effect of Compounds on PCP-Induced Locomotor Activity in Mice

Data from such an experiment using a representative compound is shown below.

As can be seen in FIG. 2, the representative compound significantly attenuated the increase in locomotor activity induced by PCP (t=4.491, df=29, n=15 veh/PCP group; n=16 Compound 4-16/PCP group). These results suggest that compounds of Formula (I) may be useful in the treatment of schizophrenia.

Effect of Compounds on Amphetamine-Induced Locomotor Activity in Mice

Data from such an experiment using a representative compound is shown below. As can be seen in FIG. 3, the representative compound significantly attenuated the increase in locomotor activity induced by amphetamine (t=3.213, df=30, n=16 mice per group). These results suggest that compounds of Formula I may be useful in the treatment of schizophrenia.

Effect of Compounds on Baseline Exploratory Locomotor Activity

The effect of Compound 4-16, a representative compound of the present invention, on exploratory (saline-treated) locomotor activity in mice is shown in below. As can be seen in FIG. 4, Compound 4-16, had no statistically significant effect on locomotor activity in mice (t=0.5793, df=30, n=16 mice per group). These results demonstrate that Compound 4-16 has no effect on exploratory locomotor activity in non-habituated, saline-treated mice. Thus, attenuation by Compound 4-16, a representative compound of the present invention, of the hyperlocomotion induced by either PCP or amphetamine is specific to PCP- or amphetamine-induced hyperlocomotion and not a non-specific decrease in locomotor activity. These results further support the potential of compounds of Formula (I) in the treatment of schizophrenia.
